Title: Disposable pre-packaged device for conducting immunoassay procedures
Inventor: LENNON DONALD J
IPC: G01N33/53
Filed: 1988-10-05
Granted: 1993-01-26
Abstract: ABSTRACT OF THE DISCLOSURE:    DISPOSABLE, PRE-PACKAGED DEVICE FOR CONDUCTING IMMUNOASSAY PROCEDURES    A disposable, pre-packaged device for conducting an immunoassay procedure.  The device comprises cup means defining a chamber for receiving liquid residues from the procedure and structure defining a liquid inlet communicating with the chamber.  Absorbent means are disposed in the chamber for promoting flow of liquid into the chamber.  Spacer means are provided in the chamber for holding the absorbent away from the inner walls of the chamber to present a breathing space communicating with the inlet and extending essentially entirely around the absorbent.  The device also includes a porous capture media element for capturing and displaying products of the procedure. The capture media is disposed adjacent the inlet of the device and in fluid communication with the absorbent.  A lid element is mounted on the cup means adjacent the inlet, the lid element and the cup means being held together by mating, corresponding annular flanges.  The lid element includes a centrally disposed cylindrical member which extends through the inlet and defines a throat positioned for directing flow of liquid assay medium through the inlet and onto the capture means.  The cylindrical member has an annular surface at its free end disposed for contacting the porous capture media means and pushing the latter toward the absorbent means and into fluid communication therewith.  The lid element flange is provided with at least one vent hole disposed in fluid communication with the breathing space to facilitate venting of the device to the atmosphere during operation.  The external opening of the vent hole and the external opening of the throat are disposed in a single plane and sealing means comprising a single planar foil element is removably adhered to the lid element in closing relationship to the openings to prevent the introduction of foreign material into the device during storage and shipment prior to use.

Abstract: The invention refers to an arrangement at a refrigerator cabinet (10) having an absorption refrigerating apparatus (16,18) operated by a heating cartridge (40) from at least one electric current source or by a gas burner (38). The arrangement shows a control apparatus (74) which automatically starts the gas burner (38) when the supply of current to the heating cartridge (40) ceases. The refrigerating apparatus (18) is with exception of its evapora-tor (16) enclosed in a heat insulated chamber (20) through which surrounding air circulates for cooling of the refrigerating apparatus (18). In order to prevent the refrigerant in the refrigerating apparatus from freezing to plugs at low temperature of the surrounding air, which plugs put the refrigerating apparatus out of function, means (86) are arranged to limit the air circulation through the chamber (20) and a temperature sensing means (80) is located in the chamber for breaking the current to the heating cartridge (40) at a certain low temperature in the chamber (20) so that the gas burner (38) is put into operation.

Abstract: An electro-optic welding lens assembly for the use in a welder's helmet or protective eyeshield comprises a filter arrangement with at least one liquid crystal light shutter element and a control unit for changing the transmission rate of the filter assembly in response to ambient light conditions. The light sensing element used to control the transmission of light through the filter arrangement is simultaneously an opto-electric transducer, supplying power to the control unit and the light shutter element. Thereby, there is no need for an additional power supply like a battery. If the sensing and transducer element is arranged behind the light shutter element, a self-regulating loop can be realized to continuously vary the transmission rate of the filter arrangement and thereby to keep the viewing illumination through the lens assembly essentially constant.

Abstract: An acyloxyacyl hydrolase from the human promyelocyte cell line HL-60 has been found to specifically hydrolyze fatty acids from their ester linkages to hydroxy groups of 3-hydroxyfatty acids, the latter being bound in turn to LPS glycosaminyl residues. The hydrolyzed fatty acids may include dodecanoic acid, tetradecanoic acid and hexadecanoic acid. This enzyme showed a molecular weight by gel exclusion chromatography between about 50,000 Daltons and about 70,000 Daltons. Altered bacterial LPS substantially without fatty acids bound in ester linkage to hydroxy groups of 3-hydroxyfatty acids covalently linked to a glucosaminyl moiety of LPS lipid A are produced. Since the structure of the lipid A moiety is highly conserved, acyloxyacyl hydrolase may act on LPS of many different pathogenic bacteria (for example Salmonella, Escherichia, Hemophilus, and Neisseria). Such altered bacterial LPS, having toxicity reduced more than immunostimulatory activity, may be therapeutically useful: (1) as vaccines to prevent Gram-negative bacterial diseases by inducing antibodies to LPS 0-polysaccharide or R-core antigens, (2) as antidotes to treat or prevent Gram-negative bacterial sepsis ("septic shock"), or (3) as adjuvants to enhance formation of antibodies to other antigens. The acyloxyacyl hydrolase itself may be prophylactically or therapeutically useful to detoxify endogenous LPS in patients with Gram-negative bacterial diseases. The enzyme may also be used to remove toxic LPS from therapeutic injectants.

Date Jan. 4, 1996The invention relates to a method for storing analysis data, especially digit analysis data in a telephone exchange (21). The data is stored as a tree-like hierarchical data structure that returns the desired result on the basis of given initial data, said data structure comprising records (11; 31; A . . . F) located in several different levels, each record comprising a predetermined number of fields (0 . . . 9, a . . . f), the uppermost level composing the root level of the structure and a single field of a record either being empty or comprising a pointer that points to the destination that may be either a record or a result in a lower level. For enabling new services of a telephone network, such as free numbering, without a continuously increasing need for memory capacity or purchases of devices, stored data is compressed by searching in a single level of the structure all the records the corresponding fields of which are pointing to the same destination, by deleting all except one of the found records and by changing the pointers of upper levels that have pointed to the deleted records so that they point to said one record, whereby said measures are started from the lowest level of the structure, after which they are repeated in the following level if necessary, until the root level is reached.
